Alternatives: "a straightforward dose of" or "an immediate dose of".
Laboratory investigations subsequently documented a direct dose-dependent enhancement of 5-FU cytotoxicity with increasing concentrations of levamisole against human cancer cell lines.
Zhou and Wallace (1999) reported that GEM and WY induced the mitochondrial permeability transition as characterized by calcium-induced swelling and depolarization of membrane potential, both of which were inhibited by cyclosporine A. Fenofibrate, clofibrate, ciprofibrate, and DEHP, on the other hand, caused a direct dose-dependent depolarization of mitochondrial membrane potential.
Detailed analysis of behavioral data suggested a direct dose-response relationship with increasing number of episodes of receptive oral-vulvovaginal sex (HR 1.02 (95% CI, 1.00 1.04).
Detailed analysis of sexual behavioral data revealed a direct dose-response relationship with increasing numbers of reported episodes of receptive oral-vulvovaginal sex.
SNPs showed strong anti-algal properties on two cyanobacteria, namely, Anabaena spp. and Cylindrospermum spp. A direct dose-dependent relationship between concentration of SNPs and cell death was observed.
Thus, there was a direct dose-response correlation between the level of bacterial phagocytosis and the amount of RACK1.
Many studies have shown that there is a direct dose-response relationship between the number of cigarettes smoked and the risk of lung cancer [ 17, 18].
To circumvent the blood-brain barrier, which prevents most molecules from leaving the bloodstream and entering the brain, Alnylam has looked to a different delivery mechanism: direct dosing of unpackaged siRNAs.
Further considerations of methodologic issues related to the conduct of the DNT study include an ILSI workshop on the direct dosing of preweaning mammals.
